Description

I'm looking at what it would take to get Accumulo working against Hadoop 3.

Thankfully, the only issue seems to be around the commons-configuration2 update that Hadoop has changed to. With our use of commons-configuration (1) for ClientConfiguration and others, this brings in multiple versions of commons-beanutils artifacts which result in exceptions at runtime.

I think the quickest solution is to just upgrade ourselves to use commons-configuration2. The "long-term" solution is to try to switch over to the shaded jars that Hadoop is publishing (but I'm reticent to sign up for that right now ).

I think we need to have a discussion about where we want to land this.
